The prototype AID system for search strategy formulation currently operational on TOXLINE is described. Utilizing a compressed in-core hash table, it relies on statistical frequency distribution information about term occurrence in a set of document texts retrieved in response to a Boolean search query, and the occurrence frequencies of the same…

Describes a method of selecting index terms directly from a word frequency list, an idea originally suggested by Goffman. Results of the analysis of word frequencies of two articles seem to indicate that the automated selection of index terms from a frequency list holds some promise for automatic indexing. (Author/MBR)

A common functional relationship among Lotka's law, Bradford's law, and Zipf's law is derived. The proof takes explicit account of the sequences of observed values of the variables by means of an index. This approach results in a more realistic and precise formulation of each law. (Author/EM)

This handy resource can be used by teachers, classroom volunteers, and parents for large- or small-group shared reading instruction. Scripted language, fun activities, and sample questions on topics such as directionality, text conventions, high-frequency words, and comprehension provide the instructor with reading strategies to support beginning…

Combine whimsical rhyming verses with practical activities that span the curriculum. Ideal for emergent and reluctant readers, this book offers: (1) repeated exposure to high-frequency words; (2) engaging opportunities for word-building, sentence development, and cross-curricular concepts; (3) fun ways to boost vocabulary and build reading…

Word government means some words are habitually used with certain constructions, which in a sense they control or govern. Because governing words are troublesome--high usage words which have acquired many meanings and usages--tabulating such words and documenting their use pay rich dividends in text processing applications.

Results indicate that a small number of high frequency words continues to dominate children's writing. However, the actual words within this core appear to indicate a noticeable change from previous studies done in the U.S.A. (Author)

Subjects learning high-frequency names had significantly better recall, confirming that color memory is a function of linguistic codability, not perceptual experience. (Author)

The question is asked: Of index terms assigned to documents, which function most effectively in retrieval, the most used or popular terms, or those which are used relatively infrequently? The experiment is a retrieval experiment and uses the Cranfield-Salton data. (14 references) (Author)

This study gives factual information on the current usage of 29 items by American writers, based on the Brown University Corpus of American English, a selection of samples of prose, coded on magnetic tape in a format accessible to computerized inquiries. (Author)
